The Croton Goldfinger plants develop their best colors when grown in bright light. As houseplants, they must be situated in a sunny window. They will tolerate medium light indoors, but won't grow much and foliage may revert to plain green.
Keep the soil evenly moist, but let it dry out between waterings. If humidity is low in your home, mist around the leaves with water once a week or keep a tray of wet gravel near the plant.
A great choice for high-light spots, croton sucks nasty VOCs from the air like a champ.
If eaten, this plant can be mildly toxic to cats and dogs.
